Ink Innovation
THINK INK
Did you know that there are many different kinds of ink, each with unique features that enhance the writing experience?
At ZEBRA, we’re serious about ink innovation and making the best pens possible, which means our Ink Lab team is always testing, innovating and perfecting ink formulas. We’d like to help you learn more about the characteristics of pens, ink types, and terminology, so the pen you choose delivers the best performance for your needs.
PEN TERMINOLOGY
Pens also have various characteristics that affect the way the pen performs – line thickness, amount of ink used, drying time, and shelf life.
Here are some “pen insider” terms, explained.

POINT SIZE
Do you want a fine line, thick line or something in between? This is determined by the “point size,” which refers to the diameter of the nib, or tip, of a pen. The sizes are listed in millimeters, and the lower the number, the finer the line. For example: 0.5mm is somewhat fine, 0.7mm is the most commonly used, and 1.6mm is quite bold.

WRITE OUT
This is just another way of saying capacity, or life expectancy, of the pen and indicates how long can you write with a particular pen before the ink cartridge runs out.

LAY DOWN
Describes how much ink flows out and is applied to the writing surface when writing. As you might guess, the bolder the line (higher point size), the greater the amount of ink is laid down.

DRY TIME
Just what you think: the amount of time it takes for ink to dry on the writing surface. Pens that lay down a lot of ink (see above) take longer to dry. Other factors that lengthen dry time are: the type paper used, the amount of pressure applied by the pen user, and type of ink. Metallic inks tend to dry more slowly. Most people want ink that dries pretty fast.

VISCOSITY
If you remember your science class, you know that fluid viscosity refers more or less to the thickness of a fluid, and in pens, it refers to how easily and smoothly the ink flows from the pen. You want a low viscosity ink to get the smoothest writing experience.
THE MAIN CHARACTERISTICS OF PENS
Found in ballpoint pens, oil based ink doesn’t smudge, lasts longer, and is a good value. It’s ideal for everyday, heavy usage. If you are writing all day long, this is the pen for you.
Hate smudges? With our breakthrough Rapid Dry Ink technology, ink dries in just a second on most surfaces, so it’s a favorite of left handers. Super smooth and available in many vibrant colors, it is perfect for creative art projects or everyday use.
So smooth! No skipping and available in bold, highly pigmented colors, this water-based gel flows freely. Fun to write with, gel pens let you express yourself with confidence.
Peace of mind. Our acid free, archival quality check-safe ink cannot be “washed” off, which means you don’t have to worry about check fraud. Also ideal for artistic creations and journal writing.
ZEBRA's emulsion ink combines the best quality of a ballpoint and gel ink pen. It has the smoothness of an oil-based ballpoint ink pen but features the vibrant colors of a gel ink pen. It has a high level of water-resistance and it’s also smear-resistant and reasonably quick drying.
